【答案】Dear Mr.Green，
I'm writing to say sorry about my delay of turning in the writing assignment you set last week.Please accept my heartfelt apology for it.
I know any word might sound a made-up excuse.But I didn't turn in the exercise for no reason.Unfortunately，my father had such a serious car accident yesterday that he had to be in hospital.Therefore，I spent a lot of time looking after him，unable to finish the article in time.I promise it will never happen again.
I sincerely hope you can accept my apology and forgive me this time.
Yours sincerely，
